Job description

About Us:

Modal provides the infrastructure foundation for AI teams. With instant GPU access, sub-second container startups, and native storage, Modal makes it simple to train models, run batch jobs, and serve low-latency inference. Companies like Suno, Lovable, and Substack rely on Modal to move from prototype to production without the burden of managing infrastructure.

We're a fast-growing team based out of NYC, SF, and Stockholm. We've hit 9-figure ARR and recently raised a Series B at a $1.1B valuation. We have thousands of customers who rely on us for production AI workloads, including Lovable, Scale AI, Substack, and Suno.

Working at Modal means joining one of the fastest-growing AI infrastructure organizations at an early stage, with many opportunities to grow within the company. Our team includes creators of popular open-source projects (e.g., Seaborn, Luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.

The Role:

We are looking for strong engineers with experience and interest in designing, building, and maintaining the novel, high-performance systems that make up our serverless platform.

Requirements:

• 5+ years of experience writing high-quality production code
• Experience building high-performance distributed systems at a large scale (the more battle scars, the better)
• Strong cloud skills
• Strong knowledge of low-level operating system foundations (Linux kernel, file systems, containers, etc.)
• Experience with performance engineering (tell us a story of when you shaved off a few milliseconds!)
• Ability to work in-person in our Stockholm office.
• Prior experience with Rust is nice to have, but not required.
